IMPROVEMENT IN REFLECTORS FOR LAMPS.

Specification forming part of Letters Patent No. 33,962, dated December 1'7, 1861.

To all whom it may concern.-

Be it known that we, WILLIAM GUsTAvUs SCHMIDLIN and J EREMIAH W. DEIsooLL, of the city and State of New York, have invented, made, and applied to use a certain new and useful Improvement in Reflectors for Street and other Lamps, Gas, dac.; and we do hereby declare that the following is a full, clear, and exact description of our said invention, reference being had to the annexed drawings, making part of this speciiicatiomwhere- Figure l is a vertical section of our reflector. Fig. 2 is an end view, and Fig. 3 is aninverted plan.

Similar marks of reference denote the same parts. v y

Our said invention consists in a divided flaring reflector located in such a manner above the flame of the lamp or. gas that the light is thrown off horizontally, or nearly so.

This invention is especially adapted to the lamps of streets, because there is nothing to interfere with the light shining down upon the street and sidewalk; but the light heretofore wasted in shining upward is thrown off by our reflector nearly horizontally up and down the streets.

In the drawings, a represents the burner of any gas or other lamp.

l) b are supports from the ring c to the re flectors d e. This ring c should be provided with the screw l, by which the parts can be clamped to the burner and the reflector held at any desired height. The reflectors CZ e are formed as truncated sections of a cone or pyramid, with the smallest ends toward each other. The supports b b are attached at these points, and hence an opening is left between the reflectors over the flame, as at f. ltwill now be seen that the reflectors d and e, al-

though sections of truncated cones or pyramids, flare away from' the llame above and on opposite sides thereof, so that the light is by the interior of these reflectors thrown olf nearly horizontally, and thus preventing the waste of light heretofore usual particularly in street lamps.

We have shown one of these reflectorsd as the section of a cone and the other as the section of a pyramid, and we prefer that the reflectors be of tin or other polished sheet metal, protected with a sheet or sheets of glass.

Where the glass is corrugated, the tin should be plain, and the reverse.

The reflector which we have shown is especially adapted to the flat flame of a gas street-lamp, and generally the light requires to be sent up and down a street, in which instance the small side reflectors l m may be applied not only to throw any light downward, but also act as connections between the reflectors d and e.

In street-lamps located atcorners and others where the light is required in four directions, two more reflectors may be employed similar to and connected with the reflectors d ve.

What we claim, and desire to secure by Letters Patent, is-

The employment of the reflectors d and e, formed as sections of truncated cones or pyramids and flaring away from the llame, substantially as and for the purposes specified.

Inwitness whereof we have hereunto set our signatures this 30th day of September, 1861.
